Mitochondrial Homeostasis and Cellular Senescence

Cells. 2019 Jul 6;8(7):686. doi: 10.3390/cells8070686.

Abstract

Cellular senescence refers to a stress response aiming to preserve cellular and, therefore, organismal homeostasis. Importantly, deregulation of mitochondrial homeostatic mechanisms, manifested as impaired mitochondrial biogenesis, metabolism and dynamics, has emerged as a hallmark of cellular senescence. On the other hand, impaired mitostasis has been suggested to induce cellular senescence. This review aims to provide an overview of homeostatic mechanisms operating within mitochondria and a comprehensive insight into the interplay between cellular senescence and mitochondrial dysfunction.

Keywords: cellular senescence; mitochondria; mitochondrial dynamics; mitostasis.
